twin IC - here it is!

[Aleman]

is there any benefit other than the fact that it's stainless steel? Harder to bend / deform is one possible theory I had but is it worth the extra investment?

I personally use Copper, and have thought about changing to SS . . . but getting a decent length one (say 100ft) here in the UK is impossible . . . In the states they used to be very easy to get (Even double coil 100ft SS IC's lovely). . . . Just because they don't tarnish, and are pretty easy to clean aggressively (Using HOT Strong Hydroxide and Acid Solutions).

The last two brewers contacts have had articles from one of the brewers at brewlab who has stated that copper is toxic, and should be excluded from brewing vessels completely as it kills yeast and eventually you. I am not convinced . . . I Know that copper screws up plant biochemistry . . . I investigated it as part of my dissertation, and yeast certainly absorbs copper, there is also evidence that breweries that went to an all SS plant had to resort to chucking a handful of copper pieces into the boiler to restore yeast performance. . . . Copper Coppers used to be common place in brewing . . . but as Peter pointed out in the article so did hazes and a copper haze is a possibility . . . .I am very doubtful and would like to see some papers with real measurements and evidence before I junked copper.

That looks good that kit,i want to have a go myself soon but i need to know if that was made without any soldering.

thanks

Ive just ordered 25m of copper tube, connectors and some just for copper - weldless copper stuff. It should be here tomorrow so ill have a bash at it and report back.

no soldering, no. I used compression joints. you could do it by soldering if you wanted to though.

[Bongo]

Cheers thanks for that.

Hey Totem did you make your 25metre twin badboy? Ive been waiting to see if you did and if youve used it cos I was wondering if its much faster than a 10metre one.
cheers

I made somthing similar but kept the connections outside the kettle, just as a precaution against leakage, it is an Extreemly Efficient cooler, I cooled 50 ltr of boiling wort down to 23 deg in about 20 min, its a bit messy and I should tidy up the pipe runs, but boy does it work well, and ya it's 25 M of 10mm.

[ADDLED]

Wow Bru, that looks the doggies. I wouldnt stand near it in a thunderstorm tho.
I dont know how fast a CFC would chill 50litres but 20 mins is pretty damn fast for what Ive read. As its more than twice the size of Gurgehs one, would it be faster if you had the cold entering in 4 places rather than 2?

[Bru4u]

I would think so but not on a linear scale, I would guess the flow may become critical beyond a point where the effect is no longer worth the effort, basicly the goal is to have the greatest surface area at the greatest temperature differential, that is why plate coolers are so much more effective than tube type coolers. The idea was brilliant, I just coppied what I read on here.

Hey ADDLED, I posted about my ic here: http://jimsbeerkit.co.uk/forum/viewtopi ... sc&start=0

But forgot to update here, i saw you've replied in that thread so thought you had the info







Ive been getting good results, taking about 6-7 mins to cool the wort! All the other information is in the other post

Hey, tks totem! I knew Id seen a 25m version of the twin cooler - lovely bit of kit.
Sometimes Im online late at night and mebbe have had a few sherbets and I see something interesting but forget to bookmark it.

I like it and want one, but i have to think about the benefit of the faster cool to justify doubling the cost of copper from 10m to 25m. That said, theres 150% more coil for twice the price.

Thing is its not for me solely. Ive been speaking with a good mate locally whos interested in HB and we may well go AG and split the cost of the kit upgrade. It makes good sense imvho and, if hes in, better IC chillers and stuff would be cool but I need to make sure there is a benefit in beer quality; I look at these things like my missus looks at handbags, but when we're spending each others money we need to justify it in less emotional terms.

Thing is, does the faster cool have any benefit on the finished beer? If it does then Im sold.

The faster the cooling, the more cold break material will settle out of the brew. It will make the finished brew slightly more clear, but there will be no difference in the taste.

[ADDLED]

tks HH. Will the difference of 5 mins in a cooldown be noticable in the clarity of the finished beer?
cheers

I've given in and made a quadruple chiller with about 12 metres of 8mm copper to see if it's quicker.

Pictures now here.

The tap water started about 21C and it took about 20 minutes to get from just-turned-the-element-out to 25C, with pumped recirculation. This is better than my 10m single coil which takes 45 or 50 minutes to do it without recirculation, but a bit disappointing. Maybe it'll be quicker with colder tap water in the winter.

I done mine a few weeks ago and it wasn't really that cold, i am happing with the 6-7 mins ive got out of mine twice.
